UK1, if they attack the fleet at 112, could send probably 1 BB, 1 CA, 1 DD for fleet. They could also send 3 FTR. This force would be against Germany’s 1 BB, 1 SUB, 1 CA, 3 FTR.
This sorta dares UK, and the fight is very balanced. Go ahead and attack with UK there, it’s fine. UK can either build 9 INF, or some fleet, but not both. That small Med. fleet is easily beatable by the Luftwaffe if they send it there, and remember Germany has 92-94 IPCs on G2 to build whatever the like. If UK combines their fleet without attacking, then SZ112 is safe anyway. If UK built INF, then you don’t need to build ships (perhaps 1 DD in case they try to defend with Subs). If UK builds ships, then you don’t need to build as many TRN to take UK. If they royally mess up and build some other strange scheme, then Germany is in luck and can easily Sealion on G3 without having to waste 2 rounds on naval builds. I think it’s pure upside for Germany…instead of always building the fleet and the huge number of transports, you build what you need given UK’s actions, and spend the rest on Russia. Conversely, if you don’t feel like attacking UK, this maneuver can still force UK to build 9 INF on UK1 without you investing in any fleet G1.
